Biography
John Mercer Brockenbrough was born in Richmond County, Virginia in 1830, and he graduated from Virginia Military Institute in 1850 and became colonel of the Confederate States Army's 40th Virginia Infantry at the start of the American Civil War in 1861. His regiment suffered 50% losses during the Seven Days Battles, and he led Charles W. Field's brigade at the Battle of Chantilly after Field was wounded at the Second Battle of Bull Run. He went on to fight at the Battle of Fredericksburg, after which Henry Heth took command of Field's brigade. When Heth temporarily assumed divisional command at the Battle of Chancellorsville in 1863, Brockenbrough returned to brigade command, and he was given a rare commendation for leading it into battle. He led it again at the Battle of Gettysburg, and his brother died in battle, while his regiment suffered heavy losses at the Battle of Williamsport two weeks later. Henry Harrison Walker took command of the brigade after Williamsport, and Brockenbrough led his regiment at Bristoe and Mine Run. He resigned on 21 January 1864 and lived in Norfolk and Richmond after the war, dying in 1892.
